I habitually don't care about things. Yeah. Why not.

But hey I mean, no one is -really- bothered by it so it's not like it matters, right?

I don't like having open drinks just sitting around, so I end up finishing them really fast. Then I am left... drinkless...
I also turn on my TV, put on a show and ignore 1/2 of it then rewind it, and watch it again, constantly missing parts and watching it over and over.

Vanelan : I have a similar thing about open drinks, except that, instead of finishing them really fast, I'll just skip cups altogether and only waterfall from jugs/2-liters when I get a drink. I mean... if it's a bottle of water or soda that I can close, it's cool, but I have to finished things like cans or cups quickly. Also, for a similar reason as yours, I don't often watch videos... Especially when I'm having one of those days where I can't focus on anything at all.

I always even since I got up at 2 AM and couldn't go back to sleep and then turned on the TV, have a weird liking for watching Infomercials. I mainly like the kitchen ones, like the Nuwave Oven and the NutriBullet, which is probably what I need for my insomnia. 

I say keep repeating like certain things I would watch a film or anything on my laptop this includes music as well. Its been a habit of mine for a while and I have just remembered that. I don't find it as bad I actually like the habit since it does benefit me well with other things I am not sure how to explain. I remember before and I didn't think on it for some reason I kept on repeating things. It would take a sibling of mine to ask me to change it to something else. Anyways that's my habit. @.@

Do suicidal tendencies and being awkward count?

Eh. I constantly crack my knuckles, I literally cannot stand still for the life of me, I constantly mouth/sing any and all songs I am hearing, I zone out all the time (day dreaming or thinking about nothingness while staring into space type of zone out.), just sorta live in my own world half the time, when I'm alone I speak a lot because I love hearing the sound of my own voice yet, like narrating my life or whatever.
Kind of obsessed with symmetry? But like not really? Like if I crack on finger on one hand I have to crack the other finger on the other hand.

I prefer laying down to standing up, and usually I use a mobile device on its side rather than facing up.
Also I usually let my entire mouth fill with a drink before I Swallow so it makes a loud gulping sound. I take large bites of food, and tend to eat fast at all times.

Well, I have a few, to say the least. For example; Rocking back and forth, Chewing on everything, Forgetting to eat, Forgetting to sleep, Random twitches, falling down whenever someone touches the back of my neck, Wearing a razor blade on an orange ribbon as a necklace, lesbianism.
Lots of strange things. But hey, It's what makes me, me.

I have a few I can think of off the top of my head.

I pretty much at all times have to be doing something with my hands. Unless I'm completely zoned out or really focused on something like watching TV, I have to keep my hands preoccupied with some mindless task. I tend to either find a small object to fiddle with (it can be a piece of string for all I care, just so long as it's something), or I'll run my fingers through my facial hair a lot, mostly just lightly tugging at the hairs on my chin. If all else fails and it won't bother anyone, sometimes I'll use my hands to play a beat on my thighs like they were a drum set lol. I do the same thing with my legs sometimes, bouncing the weight of it on the balls of my feet, or twirling my foot in circles if I have one leg propped up on the other knee. It's pretty much impossible for me to sit still.

I'm sure this is from smoking for so long and the nicotine addiction that comes with it, but along the same lines, I tend to either bite on my lip or some other form of oral fixation just to keep myself focused on something other than the nicotine itself. There's been quite a few times where I've actually bitten away layers of skin from nicotine withdrawal or being really stressed out about something. I mean it's not enough to make it bleed or anything, but enough to make it sore for a few days. 

Anytime I organize something or I'm invested in keeping it looking neat and tidy, I'm extreme anal about everything being exactly how I want it to be. I'm also terrible about doing any form of work or chore perfectly, even if it makes me take 10 times longer than I need to. Even if it's something as small as cleaning around the house. If it's not perfect, I'll waste the entire day away making sure every single speck of dust is cleaned and everything is spotless, even if it's going to be dirty again the next day. If I'm the slightest bit invested in something, I'm an overbearing perfectionist, not on others at least, but to myself.

I can't think of anything else right now, but I'll come back if I do
